I agree with Ben Framed. Unless they are absolutely busting out of the nuc, they will be too spread out if you checkerboard them all right away. If you don't mind using foundation, then I think the easiest thing to do is checkerboard the rest of the box and keep the nuc frames together. If you are looking to be foundationless though, assuming they are in a 5 frame nuc, you could maybe checkerboard just the outer 2 frames, keeping the 3 central frames together. That would give you a high chance of them drawing the frames nicely without any foundation. Definitely check weekly to be sure they are drawing straight. It's way easier to deal with crooked frames sooner rather than later.
